The Indoor Tanning Association comes to Sarah Palin's defense (via Yglesias):

While partisan bloggers and the sun scare industry will use this as an opportunity to undermine Gov. Palin and demonize the indoor tanning industry, the fact is that Governor Palin's decision to get UV light from a tanning bed positively impacts her health.

"Moderate amounts of indoor tanning allow Governor Palin to experience the many health benefits that come with exposure to UV light," said Dan Humiston, President of the Indoor Tanning Association. "Especially in dreary northern locations like Alaska, indoor tanning can help guard against wintertime depression and ward off diseases associated with vitamin D deficiency."

"Kudos to Governor Palin for standing up to dermatologists and other members of the sun scare industry who are trying to frighten Americans away from UV light."

Late Update: Hmmm ... is the Dan Humiston quoted above also the Dan Humiston (R) who ran for Congress in New York this year? So it appears. (Thanks to TPM Reader JL for the link.)
